BUG: MSDEV May Leave Orphaned Threads in the Memory After Exit

The information in this article applies to:

• Microsoft Visual C++, 32-bit Edition, versions 4.0, 4.1, 4.2

SYMPTOMS

The Visual C++ Developer Studio may leave orphaned threads in memory after exit.

The Developer Studio disappears from the taskbar on Windows 95 or the task list on Windows NT, but the process sticks around with two threads, and it is visible from PView. Notice that the Developer Studio Debugger can attach to this process in a subsequent debug session.

RESOLUTION

The Developer Studio is orphaned in memory only when switching the books in the "Select Reference" dialog box after using the F1 key. To work around the problem, change the book selection from the Help menu by choosing Open Information Title before using the F1 key for online help.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this bug and will post new information here in the Microsoft Knowledge Base as it becomes available.
